Lumens measure how much light you are getting from a bulb. The more lumens, the brighter the light.

Convection is the slowest form of energy transfer.

 


 

July 23, 2013

To help control moisture in building assemblies and materials, framing materials with moisture content greater than 19% should not be installed and should not have any signs of mold or mildew growth.

 


 

July 16, 2013

Radiation is the fastest form of energy transfer.

Save energy and money on cooling your home this summer by setting your thermostat above 72 degrees - roughly 1-3% per degree.

 


 

July 2, 2013

Moisture, in vapor form, will always move from areas with warmer temperatures to areas with colder temperatures.

 


 

June 25, 2013

To limit heat gain in the hot summer months, close blinds, drapes, shutters or shades during the day.

 


 

June 18, 2013

Install a capillary break between footings and the foundation wall to prevent moisture from migrating into it.

 


 

June 11, 2013

When forced by design to install your heat runs in an attic, consider it conditioned space and insulate at the rafters or roof deck plan. 



June 4, 2013
As temperatures rise, water your lawn and garden before 10 a.m. or after 6 p.m. — when it's cooler — to minimize evaporation.


May 28, 2013
Toilets account for roughly 27% of water used in a home! Install high-efficiency toilets (1.3 g per flush) to save water.


May 21, 2013
Up to 50% of energy costs are from heating and cooling. Insulate and seal ducts to reduce waste.


May 14, 2013
Providing shade on the southeast and west sides of a home can reduce temperatures as much as 8-10 degrees in the summer.


May 6, 2013
Take advantage of the sun by orienting the long side of a building so it faces within 20 degrees of true south.


April 30, 2013
Lighting accounts for about 6% of the energy in your home. Install sensors, dimmers and timers to reduce lighting use.


April 23, 2013
The average home spends $400-$600 heating water each year. Wash clothes in cold water and insulate hot water pipes to save money.


April 9, 2013
More than 400 studs are used in the average house. Using advanced or prefabricated systems can save lumber.


April 2, 2013
There are two types of household energy use: Seasonal (heating and cooling) and Baseload (lights, appliances, etc)


March 26, 2013
Moisture in buildings comes in two forms: bulk moisture and vapor — and it will always take the path of least resistance.


March 19, 2013
Conduction, convection and radiation are the three types of heat transfer that affect the efficiency and comfort of a home.


March 12, 2013
In a typical home, air leakage can account for up to 40% of the energy used for heating and cooling.


March 5, 2013
Compliance to the Bronze level in the energy-efficiency section in the 2012 ICC 700 National Green Building Standard® requires a 15% improvement over the 2009 IECC.
